Reliable connectivity is essential for any smart irrigation and environmental monitoring system. Our IoT Controller communicates with the Aardra Cloud platform using globally available mobile networks, ensuring the system remains independent, secure, and always connected—no matter where it is installed.

The controller supports a wide range of cellular network options, including:

• GSM

• GPRS

• CAT-M1 (LTE-M)

• NB-IoT

These technologies are widely deployed across the world and provide excellent coverage, even in challenging environments.

With our global roaming SIM card, the system can automatically connect to the strongest available network in your region, providing reliable communication with minimal setup.

For site-specific coverage queries, simply contact us and we will verify compatibility with your local mobile network providers.

Traditional IoT systems often depend on local Wi-Fi networks. However, Wi-Fi introduces several limitations:

• It requires access to the host’s router.

• It depends on the homeowner, business, or facility to maintain connectivity.

• Network changes (password updates, router replacements, guest network restrictions) can break communication.

• Many organisations do not allow external devices on their internal networks for security reasons.

By using mobile data instead, the Aardra IoT Controller remains completely independent of the host’s infrastructure.

This means:

• No router configurations

• No sharing of Wi-Fi passwords

• No dependency on local IT systems

• No risk of losing connection due to Wi-Fi outages or changes

The result is a more robust, secure, and maintenance-free communication link.

Many government bodies, councils, corporates, and high-profile projects refuse to provide Wi-Fi access to external devices.
Concerns include:

• Cybersecurity vulnerabilities

• Access control policies

• Risk of unauthorised network exposure

• Compliance with IT and data protection standards

For these environments, mobile data connectivity is the optimal solution.
It ensures full functionality without ever touching internal networks, aligning with strict security protocols.

As IoT evolves, new satellite-based IoT connectivity options are becoming available from emerging providers.
These technologies will soon enable connectivity in:

• Remote agricultural fields

• Forest or woodland installations

• Mountainous regions

• Isolated rural communities

• Sites with no mobile coverage

This advancement means smart irrigation and environmental monitoring will be possible virtually anywhere on Earth, even in locations where mobile networks are limited or unavailable.

Our system architecture is designed with this future in mind
